Coherence-induced deep thermalization transition in random permutation quantum dynamics
Chang Liu, Matteo Ippoliti, Wen Wei Ho
We report a phase transition in the projected ensemble - the collection of post-measurement wavefunctions of a local subsystem obtained by measuring its complement. The transition…
Observation of High-Order Quantum Pancharatnam-Berry Phase with Structured Photons
Shuang-Yin Huang, He Jiang, Zhi-Cheng Ren +6
When a quantum system evolves so that it returns to its initial state, it will acquire a geometric phase acting as a memory of the transformation of a physical system, which has be…
Solving excited states for long-range interacting trapped ions with neural networks
Yixuan Ma, Chang Liu, Weikang Li +4
The computation of excited states in strongly interacting quantum many-body systems is of fundamental importance. Yet, it is notoriously challenging due to the exponential scaling…
Generalized Loschmidt echo and information scrambling in open systems
Yi-Neng Zhou, Chang Liu
Quantum information scrambling, typically explored in closed quantum systems, describes the spread of initially localized information throughout a system and can be quantified by m…
